AC Installation & Replacement in Willis, Michigan

A new central air system in Willis is a 15-to-20-year decision, which is why we would rather spend an extra hour on the estimate than an extra season on callbacks. Temprasure installs properly matched R-454B condensers and coils throughout Willis, MI and the rest of Washtenaw County, sizes them with a Manual J instead of the old nameplate, and pulls the permit every time. We are roughly 18 minutes away in Ypsilanti, we offer free estimates, and we are happy to be the second opinion on a quote another company left on your counter.

Willis houses and what that means for ac installation

The typical Willis house is a 1950s–80s ranch on a crawlspace or a shallow block basement, built by a farm family or an auto worker on a piece of split-off land, and heated by a furnace that has been replaced once or twice without anyone enlarging the ductwork. Many of these were originally on fuel oil, and we still find abandoned oil tanks in basements and oil-to-gas conversion furnaces that are long past their design life. The farmhouses along Bunton and Tuttle Hill Roads are 1870s–1920s two-stories with Michigan basements and a forced-air system threaded in after the fact, usually with cold upstairs bedrooms as the result. Scattered 1990s–2010s acreage homes are colonials and ranches on full basements with 80 or 90 percent furnaces, more often propane than natural gas. Manufactured and modular homes are a larger share of the housing here than in the rest of the county, and their package units and small downflow furnaces are a regular part of our work.

The 1950s–80s rural ranches and farmhouses with scattered 2000s builds that fill Willis were built with ductwork for heat, and when central air was added later the installers usually hung a condenser on the biggest coil that would fit and called it done. Decades on, those systems are what we are replacing, and we have to correct the original mistake. On a Willis replacement we measure the return and supply trunks, check static pressure with the blower running, and size the new condenser to what the ducts can carry rather than to the old nameplate. Sometimes that means a smaller unit than the one coming out, which surprises people until they feel how much drier the house gets. Where a return is genuinely undersized we add one, because a new coil starved for airflow will freeze just like the old one did.

A cooling call in 48191 usually begins with the same sentence: it ran fine yesterday. In Willis that is almost always true, because the failure was building for a season and the hot day just finished the job. Our technicians know the 1950s–80s rural ranches and farmhouses with scattered 2000s builds along the Willis crossroads at Willis and Rawsonville Roads and the newer builds near Arkona Road area well enough to guess what is on the pad before we pull in, but we still measure. Willis has a few hundred in the hamlet, with several thousand on the Willis zip code people and a lot of air conditioners sharing a DTE Energy grid on hot afternoons, and the difference between a thirty-minute capacitor swap and a compressor quote is a meter reading, not a hunch.

Local details we plan around in Willis

• Permits for Willis addresses go through Washtenaw County's building department, and inspections are scheduled on the county's southern-township rotation.
• All homes are on septic, and high-efficiency furnace condensate needs a neutralizer or a discharge point that does not feed the drain field.
• Abandoned fuel-oil tanks and oil-era chimneys are common in the older ranches, and venting a new gas furnace into one of those chimneys often requires a liner.
• Willis is as flat as anywhere in Washtenaw County, and drainage is slow enough that ditches and field tiles run most of the spring. Crawlspaces near Paint Creek and along the lower stretches of Bunton Road stay wet into June, and that moisture finds its way into ductwork and furnace cabinets. Winter wind crosses the fields unbroken, and summer brings long humid stretches with little shade outside the old farmstead windbreaks.
